Specification of Letters Patent.

Patented Mar. 30, 1915.

Application filed March 31, 1914. Serial N 0. 828,554.

To all whom it may concern Be it known that we, JOHN A. Fnn'rz and THOMAS F. CRAVEN, citizens of the United States of America, residing at Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented new and useful Improvements in Bottle- Closures, of which the following is a specification.

This invention relates to bottle closures and particularly to that type commonly applied to jars and milk bottles.

The object is to provide a closure adapted to effectively seal the opening of the vessel while in operative position and when not in use to be moved out of alinement, with the said opening, yet remaining secured to the vessel.

Another object of the invention is to provide an improved operating mechanism for the removable closure of a bottle.

Further objects and advantages are fully brought out in the following specification, when read in conjunction with the accompanying drawing, in whichz- Figure l is a perspective view of the preferred embodiment of the invention; Fig. 2 is a vertical diametrical section of the same; Fig. 3 is a similar section in a plane perpendicular to that represented by Fig. 2; Fig. 4 is a fragmentary view of a modified form of mounting for the operating mechanism; and Fig. 5 is 0nd modified form of mounting.

Referring to the drawing, and particularly to Figs. 1, 2 and 3, a milk bottle, having a neck portion 1 and opening 2 is, provided upon its outer side adjacent to the top reinforcing rim 3 with integral projections 4:, in which are journa-led the opposite ends 5 of a wire member 6. Said member passes normally over the top of the bottle and is provided with a curved section 7 to prevent the lateral movement thereon of a second wire member 8. Said last member is looped as shown in Fig. 1 about the member 6, the intermediate portion of said member 8 being looped at 9 to form a lever for manually operating the device, while the opposite ends of the member 8 are curved downwardly and reversely, and terminating within the aperture 10 in an upwardly projecting portion 11 integral with the closure 12, said upwardly projecting portions being of an arch-like configuration. The closure 12 is also provided with recesses 13 into which the portions of the member 8 adjacent to the ends thereof are adapted to enter, to press said closure into operative position in the opening of the vessel. The top of the closure is extended to a point 13' flush with the edge of the bottle neck and has a reduced, downwardly extending portion 14 recessed at 15, to receive an annular gasket 16, which operates to make the sealing of the bottle opening air-tight.

In the modified form of the device shown in F ig. 4, the ends 5 of the member 6 are journaled in recesses 21 in the side wall 22 the bottle, while the air-tight and the under side of the extension 13 of the closure, 12. By referring to the modification shown in Fig. 5, a form of support for the closure operating mechanism is seen to comprise a wire member 25, encirclin the neck of the bottle and provided with joops 26 to receive the ends 5 of the mem- 361 6.

These are but three of the several forms which the present invention can assume and it is desired to anticipate all constructions falling within the spirit of the invention and within the scope of the appended claim.

e claim zof, an upwardly projecting centrally arranged arch-like member on the cover body and provided with a transverse opening, said cover body having a plurality of depressions in its top on both sides of the arch-like member and at the ends of the transverse opening in the arch-like member, a wire member having its extremities seated in the projections on the jar, said wire member passing upwardly over the cover body and having its central portion curved upwardly, a second wire member providing a handle and looped around the first wire member adjacent the upwardly curved portion thereof, and an operating portion formed by bending the inner ends of the second wire member downwardly to pass into the transverse opening in the arch-like projection on the cover body, portions of said operating portion being bent to extend into the depressions in the top of the cover In testimony whereof We affix our signabody prior to bending the extremities of the tnres in presence of two Witnesses. operating portion to extend into the opening JOHN A.
